The president speaks of shared sacrifice but seems to believe this does not include him or his family.  He should be required to pay for this expense out of his own pocket if he demands a separate aircraft for the dog.  I do not understand why he did not take the dog on his plane with him and his family.   Why do we the people have to pay for the these vacations anyway?  If he is not going to Camp David, the president should pay for his own vacations.
